Ama-cellulose ethers ayikilasi lamakhompiyutha e-organic polymer asetshenziswa kakhulu ezintweni zokwakha, ikakhulukazi kukhonkolo nodaka. Njengesengezo, i-cellulose ether inomthelela obalulekile ezindaweni eziningi zekhonkrithi, okuhlanganisa ukusebenza, ukugcinwa kwamanzi, amandla, izakhiwo zokubopha, njll.
1. Umthelela ekusebenzeni kahle
Ama-cellulose ether angathuthukisa kakhulu ukusebenza kukakhonkolo, ikakhulukazi ngesikhathi sokuxuba nokwakhiwa. I-cellulose ether inomphumela omuhle wokuqina futhi ingandisa i-viscosity kanye ne-rheology yekhonkrithi, okwenza kube lula ukusebenza nokuma. Lokhu kusebenza kubaluleke kakhulu ezindleleni zokwakha ezidinga uketshezi oluphezulu, njengokhonkolo opompowe kanye ne-shotcrete.
I-Cellulose ether ingathuthukisa ukuthambisa kukakhonkolo futhi inciphise ukungqubuzana phakathi kwezinhlayiya phakathi nenqubo yokuxuba, ngaleyo ndlela ithuthukise ukufana nokusebenza kukakhonkolo. Lokhu kusiza ukhonkolo ukufeza ukubunjwa okungcono nokuqedwa kwendawo ngesikhathi sokwakha.
2. Umthelela ekugcineni amanzi
I-Cellulose ether inamandla okugcina amanzi aqinile futhi isakhiwo sayo samangqamuzana siqukethe inani elikhulu lamaqembu e-hydrophilic, angakwazi ukumunca kahle futhi agcine umswakama. Lesi sici sivumela ama-cellulose ethers ukuthi athuthukise kakhulu ukugcinwa kwamanzi kukhonkolo, ikakhulukazi ezindaweni ezomile noma ukwakhiwa kongqimba oluncane. Ama-cellulose ether anganciphisa ukuhwamuka okusheshayo kwamanzi futhi agweme ukuqhekeka nokunciphisa amandla okubangelwa ukulahlekelwa kwamanzi kusenesikhathi kukhonkolo. .
Ngokwandisa ukugcinwa kwamanzi kakhonkolo, i-cellulose ether ingaphinda ikhulise isikhathi sokuphendula usimende, ivumele izinhlayiya zikasimende ukuthi zigcwale amanzi ngokugcwele, ngaleyo ndlela kuthuthukiswe amandla nokuqina kukakhonkolo. Ikakhulukazi ngaphansi kwezimo zokwakha ezomile, njengokwakhiwa kwehlobo noma izindawo zokushisa eziphakeme, ukugcinwa kwamanzi kwe-cellulose ether kudlala indima ebalulekile ekusebenzeni kokugcina kokhonkolo.
3. Umphumela wamandla
I-Cellulose ether inethonya elithile ekuthuthukisweni kwamandla kakhonkolo, ikakhulukazi emandleni okuqala. Njengoba i-cellulose ether ithuthukisa ukugcinwa kwamanzi kakhonkolo, ukusabela kwe-hydration yezinhlayiya zikasimende kuphelele, futhi inani lemikhiqizo yokuqala ye-hydration liyakhula, ngaleyo ndlela kuthuthukisa amandla okuqala kakhonkolo. Ngesikhathi esifanayo, i-cellulose ether ingaphinde ithuthukise amandla okhonkolo kamuva ngokuthuthukisa ukufana kwesakhiwo sayo sangaphakathi.
Kufanele kuqashelwe ukuthi umthamo we-cellulose ether udinga ukufaneleka. Uma isilinganiso sikhulu kakhulu, nakuba ukugcinwa kwamanzi kanye ne-rheology kuthuthukiswa, kungase kuthinte amandla okugcina okhonkolo, ikakhulukazi amandla kamuva. Lokhu kungenxa yokuthi i-cellulose ether eyeqile ingase ivimbele ukugeleza okwengeziwe kwezinhlayiya zikasimende futhi inciphise ukuthuthukiswa kwamandla azo kamuva.
4. Umphumela wokushwabana nokuqhekeka kukakhonkolo
I-Cellulose ether inganciphisa ngempumelelo ukuwohloka kokuncipha kokuqala okomile kanye nemifantu eshwabene kakhonkolo ngokuthuthukisa ukugcinwa kwamanzi kukakhonkolo. Ukuqhekeka kokuncipha kuvame ukubangelwa ukugxila kwengcindezi ngaphakathi kukakhonkolo okubangelwa ukuhwamuka okukhulu kwamanzi. Ukugcinwa kwamanzi kwe-cellulose ether kunganciphisa le nqubo, okuvumela ukhonkolo ukugcina isimo esimanzi isikhathi eside endaweni eyomile, ngaleyo ndlela ngokuphumelelayo Yehlisa ukuvela kwemifantu.
Umthelela wokujiya we-cellulose ether kukhonkolo ungathuthukisa amandla okubopha ukhonkolo, uthuthukise ukubumbana nobuqotho besakhiwo sangaphakathi, futhi unciphise nakakhulu ingozi yokuqhekeka. Lesi sakhiwo sinezicelo ezibalulekile kokhonkolo obuningi, udaka olunongqimba oluncane noma izinto ezisekelwe kusimende.
5. Umphumela wokuqina okukhonkolo
Ama-cellulose ether akhuthaza ukuqina kukakhonkolo ngezindlela eziningi. Okokuqala, ama-cellulose ether angathuthukisa ukumelana nesithwathwa kanye nokumelana nokuguguleka kukasawoti kukakhonkolo. Ngenxa yokuthi i-cellulose ether inganciphisa izimbotshana ze-capillary ngaphakathi kukakhonkolo futhi inciphise indlela yokungena kwamanzi, ukhonkolo umelana kakhulu nolaka lwangaphandle ezindaweni ezibandayo noma ezindaweni eziguguleke usawoti.
Ama-cellulose ethers athuthukisa ukuminyana nokumelana nokuqhekeka kukakhonkolo ngokuthuthukisa ukugcinwa kwawo kwamanzi nokuthuthukiswa kwamandla. Lezi zakhiwo ziwusizo kakhulu empilweni yesevisi yesikhathi eside yekhonkrithi, ikakhulukazi kumabhuloho, imigudu kanye namanye amaphrojekthi athinteka kakhulu ukuguguleka kwemvelo. Ukwengezwa kwe-cellulose ether kungathuthukisa ukuqina kukakhonkolo.
6. Umphumela wezakhiwo zokubopha ukhonkolo
Ama-cellulose ether nawo anomthelela omuhle ezimpahleni zokubopha zikakhonkolo, ikakhulukazi emandleni okubopha phakathi kodaka nongqimba lwesisekelo. Ngenxa yokuthi i-cellulose ether ingakhuphula i-viscosity kakhonkolo, kulula ukusondelana nezinto eziyisisekelo ngesikhathi sokwakha, ngaleyo ndlela kuthuthukise ukusebenza kokubopha kokubili. Lesi sici sibaluleke kakhulu ezinhlelweni ezifana nokuplasta odongeni nokulungisa amaphrojekthi adinga ukunamathela okuphezulu.
Njengengxube esebenza kahle kakhulu, i-cellulose ether inomthelela omuhle ekusebenzeni, ukugcina amanzi, amandla, ukuqhekeka kokuncipha kanye nokuqina kukakhonkolo. Ngokungeza inani elifanele le-cellulose ether, ukusebenza kukonke kukakhonkolo kungathuthukiswa ngempumelelo ukuze kuhlangatshezwane nezidingo zezimo ezihlukahlukene zokwakha ezikhethekile. Nokho, umthamo we-cellulose ether udinga ukulawulwa ngokunengqondo ngokusekelwe ezidingweni zangempela zobunjiniyela ukuze kugwenywe ukusetshenziswa ngokweqile okungase kuholele ekwehlisweni kwamandla noma eminye imiphumela emibi.
